Frequently asked questions

ZIPN is a free URL shortener that turns long URLs into memorable short addresses. Share text and files too, and choose custom codes using Korean or English letters and numbers.

Members can create permanent URL and text links. Guest links expire within one month. For member file sharing, the address is permanent, but files last 30 days up to 10 MB, 7 days over 10 MB to 1 GB, or 2 days over 1 GB. When a file expires, its stored copy is deleted and downloads stop. Upload a replacement from Edit to restart the period. Manage all links and view click statistics in your dashboard.
